The constraints are the brief
Student teachers like wide margins: full units, learning-management systems, decorative slides. A journer classroom gives you something harsher and more useful. You have a slice of a morning, two teammates, optional themes of English, Chinese, or games, and a host who knows the children better than you do. The HCIA & Journer itinerary even tells you the team size: two to three volunteers per class. A lesson briefing that ignores those constraints is a speech, not a plan.
Write the clock first. A Sunday block in the source file runs 09:30–11:15. That is not two hours of new content. It is arrival, greeting, one chunk, a game, a close, and time for the host to reclaim the room. If you plan four activities, you will trample the last child who needed the first one.
One objective, one demo, one check
Pick a single observable objective: point to six classroom objects; greet and reply; match three Chinese characters to pictures; take turns in a counting game. Demo it silently or slowly. Check it with a pair activity you can see from the back. Stop. Anything else is optional if the room is faster than you guessed.
Chinese-teaching volunteers should bring simple books because the guidebook says Bali is short of those materials. That is a content decision, not a souvenir. English-teaching volunteers should resist the urge to teach slang that the host will have to undo. Games need a rule set short enough to explain in one minute and a stop signal when the game becomes a popularity ranking.
Roles so three people are not a crowd
Assign lead voice, materials, and room-scan. Rotate each block so the same student does not monopolize both school and community-center days. The community-center session on Monday is a different room: possibly mixed ages, less furniture, more noise. Pack a shrinkable version of the same objective rather than an entirely new show.
Write a line for handing back to the host: “We stop here; thank you.” Write a line for a child who is stuck. Write a line for a teammate who is freezing. Briefs that only contain the fun parts collapse at the first silence.
Materials that survive humidity
Paper cards in a zip bag. A marker. A ball of string. A book. Not a speaker that needs an adapter you forgot, not a lesson on a phone children cannot see. Do not build the plan around photographing children holding your props. The ethics page is part of the briefing: no private gifts, no isolation, no extractive images.
Closing day is still teaching
Tuesday afternoon in the source week includes certificates and gift exchange. Rehearse who stands where, how gifts are offered with two hands, and how you thank the host by name. A chaotic exchange teaches the room that guests are disorderly. A calm exchange teaches that the week had a beginning and an end.
After the bell, debrief with your team the same day. What objective actually landed? Who spoke too much? What should the next cohort delete? Put that in the portfolio. A student teacher who cannot revise a 75-minute plan will not magically become reflective in a 2,000-word essay later.
A one-page template you can copy
- Context: school or community center; likely age band if known; language mix.
- Objective in one sentence a teammate can recite.
- Minute plan: 5 greet / 10 demo / 15 guided / 15 independent or game / 5 close.
- Roles: voice, materials, scan.
- Backup: no-projector version.
- Safeguarding: photo rule, gift rule, never alone.
- Close: thank host; reset room.
If that page is blank a week before departure, you are not a volunteer teacher yet. You are a traveler with a gap in the morning. Fill the page.
What a host teacher actually needs from you
A host does not need your philosophy of education. They need to know how long you will talk, whether you can stop, and whether your game will wreck the next period. Put the minute plan on a card they can glance at. Offer to cut. Offer to assist instead of lead if the room is already in a review. That humility should be written into the brief as a branch, not invented in panic.
If you do not share a language with the host, draw the plan. Sequence boxes. Arrows. A square for the game. Visual briefs travel. Spoken briefs die in noise. The teaching lab should practice that drawing, because two-to-three-person teams in the source itinerary will not have time for a committee meeting at the whiteboard.
After the class, the brief is not finished
Write three lines the same day: what you cut, what you would never run again, what the host added. That annotation is how a 75-minute plan becomes training. Students who throw the paper away at lunch repeat themselves on Tuesday and call it experience. Keep the paper in the portfolio. The lesson-briefing job is not to impress a mentor with fonts. It is to leave a usable trace.
If the host hands you a different plan
Use it. Your brief is a proposal. Their room is a fact. Write the change in the annotation that night so you do not pretend, later, that your original game “went well.” Submission to a better plan is a teaching skill. Students who cannot submit will fight a host for a cute activity. That fight is the brief failing in public. Put a branch in the paper: “If host prefers X, we assist.” Then actually assist.
